Heat exchangers are devices that transfer heat between two or more fluids, such as liquids, gases, or vapors, at different temperatures. They are widely used…

The figure above shows different arrangements of the shells, tubes and baffles in heat exchangers according to TEMA standard classifications. The first letter of the…
There are three basic types of shell-and-tube heat exchangers: fixed tube sheet, floating head, and U-tube. The list below summarizes the comparison between these three…
TEMA standards provide for two classes of shell and tube exchanger qualities. Class C is the less stringent and is typically used in onshore applications…
The question always comes up of which fluid to put in the tubes and which fluid to put in the shell. Consider placing a fluid…
In addition to the type description code there is also a shorthand that is used for classifying heat exchangers. The first element of the shorthand…
Tube holes cannot be drilled very close together, since this may structually weaken the tube sheet. The shortest distance between two adjacent tube holes is…
Heat-exchanger tubes should not be confused with steel pipe or other types of pipe that are extruded to steel pipe sizes. The outside diameter of…
Shell-and-tube exchangers contain several types of baffles to help direct the flow of both tube-side and shell-side fluids. Pass partition baffles force the fluid to…
Shell-and-tube heat exchangers are cylindrical in shape, consisting of a bundle of parallel tubes surrounded by an outer casing (shell). Both the tube bundle and…
